[$] Compiling Rust to readable C with Eurydice

Description:
A few years ago, the only way to compile Rust code was using the rustc compiler
with LLVM as a backend. Since then, several projects, including Mutabah's
Rust Compiler (mrustc), GCC's Rust
support (gccrs), rust_codegen_gcc , and Cranelift have made enormous progress on diversifying Rust's compiler implementations. The most recent such
project, Eurydice , has a
more ambitious goal: converting Rust code to clean C code. This is especially useful in high-assurance software, where existing verification and compliance tools expect C. Until such tools can be updated to work with Rust, Eurydice could
provide a smoother transition for these projects, as well as a stepping-stone for environments that have a C compiler but no working Rust compiler. Eurydice has been used to compile some post-quantum-cryptography routines from Rust to C,
for example.
